The answer, as recorded

## For recurring donations (what most nonprofits mean) **1. Givebutter** - My default recommendation for most small-to-mid nonprofits. Free to use with a built-in CRM, recurring giving, events, and peer-to-peer, funded by optional donor tips. If you turn tipping off you pay a flat ~3% platform fee, which is still competitive. The reason I put it first: you get real donor management bundled in, so you're not stitching a payment tool to a separate CRM. **2. Zeffy** - Genuinely zero fees: no platform fee, no processing fee, funded entirely by an optional donor contribution at checkout. Best raw economics of anything on this list. Trade-off is less depth in reporting/integrations and a checkout that leans hard on donors to tip, which some orgs find awkward. Pick this if budget is the binding constraint. **3. Donorbox** - The most polished donation forms and the strongest conversion-focused recurring features (suggested amounts, one-click monthly upgrade, fee-cover toggle). Paid tiers and add-ons (Zapier/API) cost extra, so it's worth it when donation volume justifies the platform fee. Verify current pricing directly - their fee structure has changed recently and secondhand comparisons are inconsistent. **4. Bloomerang** - Choose this when donor *retention* is the actual problem, not payment collection. It's a full donor CRM with recurring giving attached, starts around $25/month scaled to database size, and its reporting is built around retention metrics. **5. Neon CRM** - Best if you have dues-paying members, not just donors. It handles membership statuses, renewals, and recurring memberships tied to contact records, which the donation-first tools handle poorly. ## If you literally mean subscription billing (memberships, SaaS, paid services) **6. Stripe Billing** - The right baseline. Apply for Stripe's nonprofit discount: it drops 2.9% + $0.30 to 2.2% + $0.30, but you must apply, and it requires 80%+ of volume from tax-deductible donations - memberships and ticketing are excluded, which matters a lot here. **7. Chargebee** - Only if you're running true subscription products with tiers, proration, and complex dunning. Deeper subscription logic than Stripe Billing, runs on top of Stripe. Overkill for donation-only orgs, and I found no published nonprofit discount. **Short version:** start with Givebutter, switch to Zeffy if fees are the deciding factor, Donorbox if form conversion matters most, and add Neon CRM only if you have real memberships.
